1、Unit 8 Is there a post office near here? 第三課時 (Grammar Focus3c) 單元同步語法精講精練 there be句型 定義: there be句型也稱為 “ 存在句 ” , 表示 “ 某地有某人 /物 ” 。 句式結(jié)構(gòu)及用法 (1)there be句型的肯定句結(jié)構(gòu)為: There be名詞 (主語 )地點副詞 /介詞短語 (表示地點 )。 there be句型屬于倒裝句 , 主語通常放在謂語后 面 , 動詞 be為謂語 。 be動詞應(yīng)根據(jù)主語的單復(fù)數(shù)而變化 , 主語是單數(shù)或 不可數(shù)名詞 , 用 there is;若主語是復(fù)數(shù)用 there
2、are。 eg: There are 50 students in our class.我們班有 50個學(xué)生 。 (2)there be句型中的謂語應(yīng)和后面的主語保持一致 , 若有兩個或兩個 以上的主語 , 動詞 be的形式應(yīng)由最近的那個主語的數(shù)決定 , 即遵循 “ 就 近原則 ” 。 eg: There is a pencil and two books on the desk. There are two books and a pencil on the desk.課桌上有一支鉛 筆 (兩本書 )和兩本書 (一支鉛筆 )。 (3)there be句型的否定句 , 直接在 be動詞后加 n
3、ot;其一般疑問句 , 要 將 be動詞放在句首 。 肯定回答為 “ Yes, there is/ are.” ;否定回答為 “ No, there isnt/ arent.” 。 【 注意 】 如果在 there be句型的否定句和一般疑問句中有 some, 則應(yīng)將 some改為 any。 (4)there be句型一般現(xiàn)在時的特殊疑問句由 “ 特殊疑問詞 is/are there地點狀語 ” 構(gòu)成 , 有時地點狀語可省略 。 答語不能用 Yes或 No, 需 根據(jù)情況直接回答 。 eg: How many apples are there in the bag? 包里有多少蘋果 ? Fiv
4、e.五個 。 there be與 have/has的區(qū)別 there be結(jié)構(gòu)表示客觀存在 , 意為 “ 某地有某物 (人 )” ; have/has表示 所屬關(guān)系 , 意為 “ 某人擁有某物 ” 。 eg: There is a TV in our classroom.在我們的教室里有一臺電視機 。 We have a TV in our classroom.我們有一臺電視機在教室里 。 一 、 用 be動詞的適當(dāng)形式填空 。 (必要時可加 not) 1 There a park near here. 2 there any books on the desk?
